Method for pollution-free processing, recycling urban pollutant and producing regeneration product

Abstract

The invention discloses a method for treating municipal waste disposals without pollutions and manufacturing regenerative products after the municipal waste disposals are re-claimed thoroughly. The invention comprises firstly, sending fixedly the municipal waste disposals into a steam sterilizing house, sorting the municipal waste disposals into organic matters, inorganic matters, directly recoverable matters and poisonous materials as heavy metals and the like after adopting steam high-temperature sterilizations to sterilize the municipal waste disposals. The organic matters are processed into granulated organic fertilizers. The inorganic matters are processed into building materials. As for the directly recoverable matters, plastic can be squeezed into the building materials as buildingmolding plates with various shapes after being treated, materials as rubber, foamed glue and the like can be squeezed into industrial products as laying flooring glue after being treated, and waste glass can be processed into regenerative glass fibers and reinforcing filling materials which are used as the building molding plates. The heavy metals are modeled into strengthening ribs after being fluxed. Wastepaper and clothes are processed into high strength fiber plates. Cement blocks which are inserted by the poisonous materials can be used as isolating belts of high ways or retaining walls.The invention can be used to treat a great amount of waste disposals which are stored in garbage dumping fields and left by historical remnants and manufacture the regenerative products after being re-claimed thoroughly, and the regenerative products are input into markets to produce economic profits and social environmental protecting profits.

Description

technical field [0001] The invention relates to a method for treating urban garbage, in particular to a method for recycling all urban garbage without pollution and making regenerated products. Background technique [0002] At present, there are three main ways to deal with urban garbage in the world: 1. Sanitary landfill is the main way of global garbage treatment at this stage. The disadvantage is that the landfill site not only consumes land resources, but also pollutes the ecological environment, especially for groundwater and surface Water and air pollution are serious, and artificial anti-seepage technical measures are expensive; 2. Garbage incineration is suitable for areas where sanitary landfills are scarce and economically developed. 3. The high-temperature composting of organic waste and anaerobic digestion to produce biogas have the disadvantages of large floor area, difficult removal of residual residues, and secondary pollution to the environment.

[0002] At present, there are three main ways to deal with urban garbage in the world: 1. Sanitary landfill is the main way of global garbage treatment at this stage. The disadvantage is that the landfill site not only consumes land resources, but also pollutes the ecological environment, especially for groundwater and surface Water and air pollution are serious, and artificial anti-seepage technical measures are expensive; 2. Garbage incineration is suitable for areas where sanitary landfills are scarce and economically developed. Environmental pollution, and burning of recyclable and valuable materials; 3. The high-temperature composting and anaerobic digestion of organic waste to produce biogas has the disadvantages of occupying a large area, difficult to remove the remaining residues, and secondary pollution to the environment
